I am a huge fan of SB leggings and own more pairs of the power version than I'd like to admit! However I needed a zip-free pair so thought I'd opt for these. Sadly they are hopeless, they slip down constantly so I'm forever pulling them up and doing any classes in them in is a non-starter. Also the weird bulky seam/stitching that stops mid thigh is seriously unattractive. It's the first time I've ever been disappointed with a Sweaty Betty product, but I seriously am.
